AUTOMATIC LUBRICATING APPARATUS FOR FOIL-MILLS,

SPECIFICATION forming part of Letters Patent No. 425,795, dated April15', 1890. Application filed January 20, 1890. Serial No, 337,48'0. (Nomodel.)

To all 2071 0722, it may concern:

Be itknown that I, ALBERT G. lIoTcHKIss, a citizen of the United States,residing in the city and State of New York, have invented an Improvementin Automatic Lubricating Apparatus for Foil-Mills, of which thefollowing is a specification.

In the manufacture of tin and other metallic foil it is usual to makeuse of soap-water 01' similar lubricating material applied to thesurfaces of the rolls between which the'foil is passed, in order thatthefoil may not adhere to such rolls, and in some instances thelubricating-liquid has been applied to the roll or web of foil as it ispassed into themachine.

The lubricating-liquid has usually been applied to the rolls by brushesin the hands of an attendant, and the operation is often im-' perfectlyperformed by the unskilled labor of boys. I

By my present improvements both the rolls are kept lubricated in themost perfect and uniform manner automatically, thus rendering theoperation of the foil-mill much more perfect, and at the same timelessening the expense, and I make use of a peculiarly-constructed holderfor the roll of foil, so that the same can be supplied with lubricatingmaterial upon the surface of the foil previous to the same passing inbetween the rolls.

In the drawings, Figure 1 is an elevation, partially in section, one ofthe frames being removed, representing the-automatic lubricatingapparatus as applied to a foilamill. Fig; 2 is a separate sectional planview of the brush, andFig. 3 is a diagram of the connections between thesoap-water tank and the brushes.

The rolls A B are supported in the frames t. (1 and driven in any usualor desired manner. Usually gear-wheels are made use of, and-the sheetor. web of foil from the roll D passes in between the tension-bars 2 34, one of which is provided with disks at opposite edges of the sheet offoil to form guides.

The roll I) for the foil is supported atits ends in the vertical holdersE, the lower ends of which are received into the transverse trough-bedl* upon a bracket F, extending out from the base C of the frame (I C,and there is a screw 6 passing through the lower ends of the holdersE,-\\'hercby such holders E can be adjusted transi'ersely of the machineand within the trough-bed F, so that the roll of foil I) may bepresented at the proper place between the two rolls A B.

The water-trough G is made with sides 7 and a curved back 8 and'wit-h adownwardly projecting spout 9, and it is of a size adapted to setbeneath the roll of foil, so that the soap-water running regularly uponthe foil from a pipe 10 will spread upon the surface of the foil, andthe surplus soap-water will run down by the spent 9 into areceiving-tank beneath the rolls A B and can be used over again bypumping it up into the tank IL The lubricating brushes L M are eachformed with a head 11, to which isconnected a pipe N, with nozzles 12passing in between the bristles of the brush, so as to-constantly supplythe lubricating-liquid through such pipes and nozzles to the surfaces ofthe rolls, and the liquid is spread with uniformity by the action of thebristles of the brushes, and in addition an end motion is given to suchbrush,as hereinaftersetfortlnsothatthobrush is made to act regularly anduniformly from end to end along the surface of the respective rolls.Each brush is provided with an arm 13, pivoted at one end to a stock Por P, and there is a spring 14 between the stock and the arm to pressthe brush toward the roll, and this spring yields to allow the brush tomove away from the roll Without being inj ured should the foil atanytime wind around the roll itself. The upper stock P is longer thanthe lower stock I, so as to extend up out of the way.

Thestocks l P are preferably slotted and held by the clamping-screws 15to the headpieces Q (3' upon the reciprocating bars R R, and thesereciprocating bars are within bearers or boxes 16 upon the frames 0 O ofthe machine, and there is a rocking lever S, pivoted at 17 and connectedby links 18 to the ends of the respective reciprocating bars R R, and inthis rocking lever is a slot 19 for the crank-pin 20 upon therevolvingwheel T, to which a continuous revolution is given at the proper speedby any suitable power, and the crank-pin 20 is adjustable nearer to, or

farther from the center of the revolving wheel '1, so as to give greateror less motion to the rocking lever S, in order to move thelubricating-brushes longitudinally of the rolls to whatever extent isdesired, and it will be noticed that these reciprocating brushes and thebars that hold the same are above and below thefoil as it passes inbetween the rolls, and hence they do not interfere with thefoil and arenot in the way' of the workmen as they are attending to the introductionor removal of such foil, and the cross-bars Q Q between the frames C Oserve as guides to the head-pieces Q Q as they are reciprocated.

The soap-water tank H is preferably provided with a thermometer 21 and aglass tube 22 for indicating the level of the water in such tank, andthe discharge of the soap-water is regulated by the valve 25, and fromthis tank pipes H either partially or wholly flexible, extendtto thepipes N upon the brushes. I have represented these pipes H as flexiblebetween the couplings 26 and the pipes N upon the respective brushes.

By this improvement the surfaces of the rolls A and B will be uniformlylubricated by the action of the reciprocating brushes and soap-water orsimilar liquid, and'the tension of the foil as it passes in between therolls will be determined by the number of bars 2 3 4 around which thefoil passes, as usual,

and in consequence of the web or sheet of foil being moistened uniformlywith soapwater or similar lubricating material the tension-bars will bekept in the proper condition, so that they will not injure such foil.

I claim as my invention- 1. The combination, with the rolls in afoilmill, of a reservoir or holder for soap-water or otherlubricating-liquid, and brushes, and stocks for supporting such brushesin cont-act with the rolls, and pipes leading from the reservoir to thebrushes forv supplying the lubricating material, substantially as setforth.

2. The combination, with the foil-rolls, of a brush, ahead for the same,a rcservoiror holder and a pipe for supplying lubricatingliquid to thebrush, an arm attached to the brush, a stock to which the arm is hinged,

and a spring for pressing the brush toward the roll, substantially'asset forth.

3. The combination,.with the foil-rolls, of brushes, a reservoir andpipes for supplying the lubricating-liquid to such brushes, bars brusheswith lubricating material in contact with the respective foil-rolls. andyielding arms connecting the brushes with the reciprocating bars,substantially as set forth.

5. The combination, with the foil-rolls and the frame for the same, ofthe bracket F, extending out from the baseof the frame, the

transverse trough upon the said bracket, the

vertical holders E and screw 6, for adjusting the holders, and a rollfor the foil, substan tially as set forth.

6. The combination, with the foil-roll, of the water-trough G, adaptedto set beneath and at the ends of such roll and provided with a spoutfor the lubricating material, and the foil-rolls and frame having areceiver for the lubricating material in the lower part of such frame,substantially as set forth.

Signed by me this 10th day of January, 1890.
